摘要
研究了聚乙烯醇（PVA）／聚丙烯腈（PAN）、海藻酸钠（SA）／PAN复合膜及海藻酸钠／醋酸纤维素（CA）共混膜等五种膜的渗透汽化特性，发现它们对正丁醇／水的混合液均表现为水优先透过，其渗透通量与选择分离系数都很高。并初步确定了正丁醇／水混合液渗透汽化分离的工业生产操作条件。
The pervaportation characteristics of PVA/PAN, sodium alg-inate / polyacrylonitrile composite membrane and SA / CAblend membrane were investigated. These membranes prefere-ntially permeated water from the BuOH-water system bypervaporation. The values of total permeation rate and separ-ation factor were very high.
